To all fte/"wm may concern.'

Be it known that l., DUNCAN D. MCBEAN, a citizen ot the United States,residing` at New York. in the county and State of Newv `adjustthemselves to the lforms oit.' the undulations of the waves,consequently the movement in their joints is a weakness in them whichsooncauses their destruction.

This invention resides in a new means of transporting lumber and timberover` water routes, without the use oit' the ordinary means ottransportation suoli as the ships orv barges which are now built andused for that purpose.

This invention consists in building up in or on the water a cargooi"iinber and lumber and assembling it into a rigid bodyhavn ing theform of the hull of a ship, in which all the space within it is filledsolid with lumber and timber, except where waterproofed spaces within itare required above the bottom tier of timber forming the bottom of thehull.` This ship may be propelled by the use of machinery o r by the useot sails as in an ordinary ship, or by the use of both.

In carryingout this invention l construct the timber ship in the mannerwhich Iis more specifically herein described, but this description. aswill be understood is of a specilic embodiment of the broader idea.

The speoiiic manner in which l prefer to carry out the invention isillustrated in the accompanyingi drawings in which.: n

Following in some detaittheproposed:

plan of Construction I first assembleon the surface of a convenient bodyof water,

courses of rather heavy timbers forniii'irllfav tier A, I unite the keeltimber Kto the center pieces of tier A by boltsha.' Then'I lay on top oftier A, a. certain number of the transverse tier of timbers B,bolting-one end of the latter to the outside course ot timber in tier Aby bolts b. By any suitable' means...

the corners of timber forming tier A 'are then forced firmly together ina leveltier,z

and the opposite ends of the superii'nposed timbers are secured bybolt-so to the opposite outer timber in tier A. f

Upon tier A71 then place upright side-ry timbers C., and a center lineof upright timl bers D, securing by bolts d through' the lower endsthereof to the transverse'timbers in tier B. and the outside uprights'are bolted also to the outside planking E. y

At this stage, I yalso yplace atv suitable .in-

tervals upright timbersialong the center line to serve as masts F. Theheight of the side upright timbers is such that they will extend abovethe contemplated deck G of the ship, suiiiciently to constitute supportsfor: the bulwarks and rail H: that of the center upright timbers D, suchas to permit'of longitudinal timbers I, above the deck to be secured tothem. and the portion of the mastv timbers above the decl; are to berounded or dressed to permitof'their proper use with tackle and sails.

After the upright timbers areiplaced` and .y l.

fastened in the manner described, the second tier of bottom timbers iscompleted. by

lilling in the spaces between the timbers B with' others ot the samethickness, land plankiiirg E is secured to the outs-ident' the saiduprights. A third `tier of longitudinal bottom timbers tlF .is then laidon and transversely those of the second tier. i y

Generally three, tiers of bottoni `timbers lil@ are ample for a largeship. 'The ends of the timbers of the second tier may all be bolted vtothe lower and superimposed tit-iroiitinibers, oronly a portion of themas be found necessary and desirable.` When the' second tier timbers Bare in Contact with; the

center iipr'ights D and masts F they may be secured by bolts i to thelatter. and the lon- A.oit-udinal timbers alongside the said uprightsandmasts should be held together by bolts e that pass through the-latter.

The lengths of the pieces of timber placedI longitudinally, and formingthe courses of the third tier of timbers J are made longer or shorterthan those below them in the first or bottom longitudinal tier oftimbers A. All the ends of timbers in the bottom tier are held by boltsto the timber above it in the thirdtier, and all the endsof the timbersforming the third tier are bolted to the timbers below them in the firsttier. rlhe courses of timber which lie adjacent to the center uprighttimbers in the fourth course are not only bolted to the center uprighttimbers but are also secured by bolts z' to the keel piece under thefirst tier, and those lying adjacent to the side upright timbers arefastened by bolts j to the outside courses of timbers on the outside ofthe first tier, thus breaking joints and bolting the bottom four coursesand keel together and tying` them to the upright timbers. The courses oftimber placed longitudinally forming the first and third tiers oftimbers in the bottom are made longer or shorter than their neigh` borsat their sides, thus toothing the courses and breaking jointshorizontally across each tier. In some cases it'may be desirable to havethe bottom tier started With a transverse tier instead of'a longitudinaltier as shown in Fig. Q, then reversing the order of laying the firstfour tiers of timbers in the hull.

'-It is preferred to have all timbers, except those in the lonercourses, that are bolted to the upright timbers, clamped or forced downhard on the timber and lumber underlying them before bolting them so asto prevent looseness in the oints an'd secure rigidity to the structure.

After the three tiers of bottom timbers are laid, transverse timbers L(see Figs. 2

filled solid with timber as theplanking isV bui-lt up..

The timbers and lumber constituting the cargo are rthen stowed on thebottom tiers between the Walls of planking M, thus forming-.the body ofthe hull of the ship. As

the cargo timbersare placed between the Walls of planking M it is laid,preferably,

in tiers of even. thickness, and so as to break.

' joints Vand interlock as far as'possible.-

When'a-pile' of timber or-lumber ofthe desired thickness has thus.l beenstowed,

cross-, timbersl ,.G, extending ,entirely across .Its transportat-ion.*riskV is limited to the loss `4 the ship are secured to theside nprights and secured by bolts 7L to those in the center, which tiethe ship together and bond the cargo to the tier of bottom timbers.

In this Way the hull of the ship is built up to the level of what isintended to be the deck, Where the final tier of cross timbers G issecured in place. Along the entire length of the deck heavy longitudinaltimbers I are then laid against both the side and center `line uprightsand firmly secured by bolts k thereto. The projecting side uprights areplanked on the outside to form the buln'arks and rail H.

In the construction of the hull of the ship, such keel as may benecessary is built on or formed with the under tier of timbers,.and suchof the central longitudinal timbers as may be necessary are caused toproject at. the stern to form supports or bearings for a rudder post.The bonv and stern may be formed of any desirable shape.

As intimated above, a boivsprit, if necessary, is built in with thecargo, and such shronds, stays, sails and the like, with means, Whendesired for Working the latter, are added. On the deck, houses may bebuilt for the crew, for the necessary engines, for supplies and the likeof a suitable number and capacity.

Should it be desired, any portions of thestructnre may be left as emptycompartments, in which case the walls thereof must be made ivatentight.or the entire ship may be made Water-tight by the use of courses ortiers of Water-proofing character of any suitable nature.

With thel details of this and other like features, thepresentapplication is not particularly concerned they are matters thatthose skilled in this art may adopt and use Without the exercise ofinvention. p My main purpose as indicated by thecontextis to transferlarge cargoes of timber and lumber over 4water routes with displacementsj only sufficient t'o float them, by assembling each cargo, on theWater, into the form and outlines of theA hull of an ordinary ship thatis filled solid with a'cargo of timber and y lumber, which maybepropelled by the use of machinery, or as a sailing ship,l or by the useof both, thus avoiding the building of the hull of the ship or anypart-bf it`on shore and launching it-, thereby saving a` v largeexpense, and j iermitting the hull to4 c be made far more rigid thanispracticable by the .usual method of building hulls of ships, thus,enabling the assembling' of a cargo :of lumber intovthe form and'out-llines of the hull of a ship at a cost .not much more'th-an that of theloadingof it into the several ordinary ships that arenccessary to carrythe large cargo, anda saving of time.v

ofthe cargo Without the'additional risk o outlay of capital representedby the several ordinary ships necessary to carry the cargo is avoided. Asaving is madeof the cost of the expenditure ofpower necessary to propelthe Weight of the extra displacement of the ordinary ships above thatrequired to floatonly the cargoes of lumber and timber Within them. Thedelivery ofthe cargo is.

practicable to be made immediately on its arrival in the harbor of itsdestinatin, instead of havingto Wait to unload it. It may be unloaded at'a less cost than that of unloading it -from ordinary ships, and Withoutincurring the cost of demurrage usually paid to ships for delays inunloading their cargoes.

What I claim as my invention and desire to secure by Letters Patent is:

- l. A timber ship by means of which lumber and timber in quantity maybe transported by water, composed of a cargo of such lumber and timber Yassembled in' a series of transversely laid tiers and temporarilysecured entirely by its own members in a substantially solid raft havingthe lines of a ship which permit it to be propelled by machinery or inany wind by sails, and which is adapted in .unloading to be completelydismembered, to utilize all of the lumber and timber used in itsconstruction.

2. The method herein described of associ;

ating for the purpose of transportation by Water, a cargo of lumber 'ortimber, which consists in assembling such cargo on the Water, layingtogether therein tiers-of the same to .form the bottom of asubstantially solid mass, building upfrom such bottom by means ofupright timbers the frames for the sides and ends, filling the interiorprogressively from the bottom as the structure sinks, and tying, bindingand bracing the structure by means of the timbers and planking laidtransversely in tiers and temporarily fastening devices securing thesame Where necessary.

3. The method herein described of associuprights, cargo ating for thepurpose of transportation by Wat-er a cargo of lumber and timber, which,pnsists in assembling the cargo, associating bn'the water and securingtogether while `floating a plurality of tiersor coursesl of timber toform a bottom, erecting-upri hts along the side and central lines of theottom, applying side Walls of lanking to such uprights, tying together te structure by means of such uprights and'longitudinal and transversetimber, while progressively buildingl up into a substantially solid massthe entire cargo with all its members capable of being dissociated andused. A

4. The timber and lumber ship herein described comprising a plurality ofbottom,

ltiers of timbers, the alternate' tiers being `iaid at right angles toeach other, and `all securely fastened together, side and center lineuprights resting on and secured to the bottom timbers, p lanking wallssecuredto the uprights, formmg side and center keelsons throughout thehull abovey the tiers of timber forming the bottom of the ship, andlongitudinal and transverse tyin and alongside the upright timbers.

5. `The timber and lumber ship herein described, comprising a pluralityof oppositely laid tiers of bottom timbers, secured together, side andcenter line uprights resting on and secured to such` bottom tiers, wallsof planking secured to the uprights, cargo lumber stowed solidly betweensuch walls and transverse and longitudinal tlmbers secured to theuprights for tying and bonding together the several portions of the-hull of the ship.

' 6. The timber and lumber ship herein described, comprising a pluralityof oppositely laid tiers of bottom timbers, secured together, side andcenter line uprigbts, resting on and secured to such bottom tiers atintervals, walls of planking secured to the lumber stowed solidly be-ltween such walls, transverse and longitudiy nal timbers secured tothe`uprights for tying and bonding together: the several -portions ofthe hull of the ship.
